Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands. Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera.
Recombinant DNA Technology. Recombinant DNA Technology. All organisms on Earth evolved from a common ancestor, so all organisms use DNA as their molecule of heredity. At the chemical level, DNA is the same whether it is taken from a microscopic bacterium or a blue whale.As a result, DNA from different organisms can be âcut and pastedâ together, resulting in ârecombinant DNAâ. The first recombinant DNA molecule was produced in 1972 by Stanford researcher Paul Berg.f the DNA from the different sources is cut with the same restriction enzyme, the cut ends can be joined together and then sealed into a continuous DNA strand by the enzyme ligase. In 1973, the first organism to contain recombinant DNA was engineered by Herb Boyer (UCSF) and Stanley Cohen (Stanford University).
